Step 1: Let's review the information given to us to solve this problem:
Rent of the apartment = $ 755
Amount Isaiah receives monthly = $ 250
Wage per hour = $ 10
Step 2: Let's write the inequality to find the number of hours Isaiah must work to pay the rent, as follows:
Let x to represent the number of hours Isaiah works
10x + 250 > 755
Subtracting 250 at both sides:
10x + 250 - 250 > 755 - 250
10x > 505
Dividing by 10 at both sides:
10x/10 > 505/10
x > 50.5
Isaiah has to work more than 50.5 hours
